Here's a CoCo1 Technical Manual...

I think this is for an early revision (C or D) board.

I understand...

The article is in the RTSI\OS9_6X09\HARDWARE folder.
If you think the 8808 chip could work, I've already
located a source. Email me privately for details.
But you can probably simulate this chip too, no?

It sounds like a pretty cool project! I'd like to
offer my help in any way possible.
